Here's another real world example, although it was in C: char* ptr; assert( ptr = malloc( memsize ); )
Of course, this worked when built in debug, but it took a while to track down why it wasn't working in the release build (the assert()'s were stripped out in the release builds, so ptr didn't allocate any memory). Unfortunately, the runtime failure happened in an entirely different part of the code, since ptr wasn't initialized to null, so this particular routine just merrily stomped on whatever memory address happened to initialize in ptr. -- Paul -- http://mail.python.org/mailman/listinfo/python-list
